Check coverage before you port
Ultra Mobile runs on the T-Mobile network, so the coverage you get at your address is T-Mobile coverage. Check it on T-Mobile’s own coverage map before you start the transfer.
Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.
